Propylene Refinery Grade (P-P mix)

Where It's Made

Chevron Phillips Chemical produces 3 billion lb/yr of polymer grade propylene at its facilities in Cedar Bayou, Port Arthur and Sweeny, Texas. Propylene is probably the oldest petrochemical feedstock in the gas industry. Propylene, also known as 1-propene, is one of the smallest stable unsaturated hydrocarbon molecules used in the gas industry.

How It's Made

The propylene molecule is produced as a co-product of ethylene production through the steam cracking (steam pyrolysis) of hydrocarbon feedstocks. Feedstocks used for steam cracking range from ethane to naphtha and gas oils. Propylene is also produced as a by-product of petroleum refining. Propylene is sold in three separate quality grades: refinery (~70%), chemical (~92-96%) and polymer (99.5%). Chevron Phillips Chemical sells refinery and polymer grades.

How It's Transported

The propylene is stored in large underground caverns and transported through the propylene pipeline system, which measures about 150 miles. Propylene is transported internationally via vessels and domestically by pipeline, railroad and truck.

What It's Used For

Propylene is used mainly to produce polypropylene plastics for injection molding and fibers and for manufacturing cumene (used in phenol production). Propylene is also used to make propylene oxide, acrylic acid, oxo alcohols and isopropanol.
